Under the leadership of Victor (Billy Nighy), the blood clan traveled alone in the world, and the powerful blood-sucking corps suppressed the brutal wolf clan that was highly contagious and could not evolve into humans. Until one day, a magical life was born, which changed the fate of the two families. A female wolf gave birth to a werewolf Lucien (Michael Sheen) with a human appearance. Victor saw the powerful strength in the werewolf's body, so he bred a large number of them and made them slaves to serve the blood clan. The suffering of slaves will never end, and in this process Lucien also secretly fell in love with Victor's daughter Sanya (Rhona Mitra) despite the world's disapproval. Lucien, who longed for freedom, finally managed to unlock Victor's imprisonment of himself, and the war between the werewolves and the blood clan that lasted for hundreds of years also kicked off...
